This PopTiki Volcano Mug was designed and manufactured by Glen "PopTiki" Helzer. It is black with lava around the top rim. Originally the lava was glazed orange, but in 2008 the lava glaze was changed to red. The mug has a hole for a straw and a small reservoir on the rim for either dry ice or flame. The first run of this mug was limited to 14 mugs, but this design (with current red glazed lava) is an open edition.
